If your engine mounts so that the backplate faces out (I'm assuming) then you can use a drill. As dbow says leave the bearing in the socket, not on the engine. You might be interesed in a yank eliminator. They have a bearing inside that stays on the yank elimintor with no possibilites of it getting stuck on the engine. Here's the tower hobbies link.
